Description

Technical Field

[0001] This utility model relates to the field of steel component processing technology, and in particular to a punching device for steel component processing. Background Technology

[0002] In steel component processing and installation, to meet the connection, assembly, or functional requirements of steel components, it is often necessary to drill circular holes of specific specifications on the steel components. Handheld punching devices have become commonly used equipment for such punching operations due to their advantages of high portability and flexible operation. The structure of existing handheld punching devices typically includes a punching machine body, with a punching rod extending from the end of the punching machine body to transmit punching power. The end of the punching rod away from the punching machine body is fixedly equipped with a punching die—the die is usually fixed to the punching rod by bolt fastening or integral molding. In actual operation, when using existing handheld punching devices to punch holes in steel components, the core steps are: first, accurately fitting the punching die onto the part of the steel component to be punched; then, the operator holds the punching machine body and drives the punch to move into the punching die and contact the steel component, thus completing the punching. However, in many practical application scenarios, the installation location or placement space of the steel component is significantly limited—for example, the steel component is placed near walls, equipment casings, other steel structures, or other obstacles, or the steel component itself is located in a narrow installation cavity. In this case, in order to successfully fit the punching die onto the part of the steel component to be punched, the operator needs to adjust the position and posture of the punching machine body to avoid obstacles and adapt to the die fitting position. However, because the punching die and punching rod are fixedly connected in existing devices, the position of the punching machine body must be adjusted synchronously with the die's placement. After adjustment, the punching machine body is often in a position that is difficult for the operator to hold comfortably: the operator may need to bend or twist their hand to avoid obstacles, or space constraints may prevent the hand from fully covering the gripping area of ​​the punching machine body. This inconvenience not only significantly increases the difficulty of operation and reduces the efficiency and convenience of punching operations, but may also cause the die to shift during punching due to an unstable grip, affecting the accuracy of the hole position; moreover, improper gripping posture can easily cause operator hand fatigue, increasing the possibility of safety risks caused by operational errors, making it difficult to meet the actual needs of punching steel components in confined spaces. Therefore, there is an urgent need for a punching device for steel component processing that can flexibly adjust the position of the punching die, so that when punching round holes in a confined space, only the position of the punching die needs to be changed to ensure that the punching machine is in a position that is easy for the operator to hold, thereby improving the convenience of operation and ensuring the punching effect. Utility Model Content

[0003] The purpose of this utility model is to provide a punching device for processing steel components, which can flexibly adjust the position of the punching die relative to the punching machine, ensuring that the punching machine is in a position that is easy for the operator to hold, improving the convenience of operation, and ensuring the punching effect and operational safety.

[0004] The present invention adopts the following technical solution: A punching device for processing steel components includes a punching machine, a punching die is provided on a punching rod at the end of the punching machine, the punching die is rotatably connected to the punching rod, wherein a positioning element is provided between the punching rod and the punching die, and the punching die is in a stable state under the action of the positioning element during operation.

[0005] Preferably, the positioning element includes a positioning sleeve elastically sleeved on the punching rod, a connecting sleeve fixedly provided at the top of the punching die, the connecting sleeve being rotatably connected to the punching rod, and positioning teeth and positioning grooves that mesh with each other provided on the end face of the positioning sleeve that contacts the connecting sleeve.

[0006] Preferably, the punching rod is fitted with a positioning spring, the top end of which is connected to a positioning plate on the punching rod, and the bottom end of which is fixedly connected to the top end of the positioning sleeve. In the initial state of the positioning spring, the positioning sleeve is in close contact with the connecting sleeve.

[0007] Preferably, the punching die consists of an upper die sleeve and a lower die sleeve, and the upper die sleeve and the lower die sleeve are slidably adjustable.

[0008] Preferably, both the upper mold sleeve and the lower mold sleeve are L-shaped. The upper mold sleeve has a sliding groove, and the lower mold sleeve has a slider that matches the sliding groove. The upper mold sleeve is threaded with a positioning bolt, which passes through the sliding groove and is threadedly connected to the slider.

[0009] Preferably, the upper mold sleeve has an adjustment groove, and the positioning bolt is threadedly connected to the slider through the adjustment groove.

[0010] Preferably, the upper mold sleeve has a receiving groove, and the adjusting groove is located in the receiving groove.

[0011] Preferably, the bottom of the punching die is detachably provided with a receiving box, which is connected to the lower die head located at the bottom of the punching die.

[0012] Preferably, the bottom of the punching die is provided with a placement groove, and the receiving box is slidably disposed in the placement groove.

[0013] Preferably, the bottom surface of the receiving box is higher than the bottom surface of the punching die.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By designing the punching die and punching rod to be rotatably connected, this utility model breaks through the structural limitations of the fixed connection between the two in existing devices. In space-constrained scenarios such as steel components near walls, equipment shells, or in narrow cavities, operators do not need to adjust the position and posture of the punching machine body; they only need to rotate the punching die to accurately fit it onto the part to be punched. At the same time, the punching machine body can be kept in a comfortable grip position for the operator, avoiding hand bending, twisting, or inability to fully cover the grip area. This fundamentally solves the problem of inconvenience caused by space constraints in existing devices, greatly reduces the difficulty of operation, improves work efficiency and safety, and ensures the punching effect.

Detailed Implementation

[0016] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments: like Figures 1 to 4 As shown, the present invention discloses a punching device for processing steel components, comprising a punching machine 1, a punching rod 2 at the end of the punching machine 1, and a punching die 3 rotatably connected to the punching rod 2. A positioning element is provided between the punching rod 2 and the punching die 3, ensuring the punching effect by keeping the punching die 3 stable during operation. This invention, through the rotatable connection between the punching die 3 and the punching rod 2, eliminates the need for repeated adjustments to the main body position of the punching machine 1; the setting operation can be completed simply by rotating the die, reducing operation steps and adjustment time, and significantly improving punching efficiency. Furthermore, it allows operators to maintain a comfortable grip, avoiding hand fatigue caused by improper posture and reducing the safety risk of operational errors due to hand soreness. This provides safety assurance for long-term or batch punching operations and reduces the labor intensity of operators.

[0017] Furthermore, the positioning component includes a positioning sleeve 4 sleeved on the punching rod 2. A positioning spring 5 is fixedly installed on the upper part of the positioning sleeve 4 by welding or bolting. The top of the positioning spring 5 is fixedly connected to the positioning plate 6 set on the punching rod 2 by bolting or welding. A connecting sleeve 7 is fixedly installed on the top of the punching die 3. The connecting sleeve 7 has a through structure and is connected to the upper die head 8 at the top of the punching die 3. The two are arranged coaxially to ensure the smooth movement of the punch during the hole-opening operation. The connecting sleeve 7 is rotatably connected to the punching rod 2 by bearings. The end faces of the positioning sleeve 4 and the connecting sleeve 7 that contact each other are provided with mutually meshing positioning teeth and positioning grooves. The positioning teeth and positioning grooves are arranged along the circumference of the end faces of the connecting sleeve 7 and the positioning sleeve 4. The meshing of the positioning teeth and positioning grooves can ensure the stability of the punching die 3 in the initial state. When the positioning spring 5 is in the initial state, the positioning sleeve 4 and the connecting sleeve 7 are in close contact through the positioning teeth and positioning tooth groove. When it is necessary to adjust the punching die 3, the positioning sleeve 4 is pulled up to disengage the positioning teeth from the positioning tooth groove. The structure is simple and the operation is convenient and quick.

[0018] Furthermore, in this embodiment, the punching die 3 consists of an upper die sleeve 3-1 and a lower die sleeve 3-2, and the upper die sleeve 3-1 and the lower die sleeve 3-2 are slidably adjustable. This allows for adjustment according to steel components of different heights, thereby expanding the opening range of the punching die 3 and increasing the applicability of the device. Specifically, both the upper die sleeve 3-1 and the lower die sleeve 3-2 are L-shaped. The upper die sleeve 3-1 has a sliding groove 9, and the lower die sleeve 3-2 has a slider 10 that matches the sliding groove 9. A positioning bolt 11 is threaded onto the upper die sleeve 3-1, and the positioning bolt 11 passes through the sliding groove 9 and is threadedly connected to the slider 10. At this time, the end of the positioning bolt 11 is in close contact with the wall surface of the upper die sleeve 3-1 to ensure the stability of the connection between the upper die sleeve 3-1 and the lower die sleeve 3-2. Preferably, the upper die sleeve 3-1 has an adjustment groove 12, which is opened along the length of the sliding groove 9. The positioning bolt 11 passes through the adjustment groove 12 and is threadedly connected to the slider 10. The adjustment groove 12 enhances the flexibility of adjusting the upper die sleeve 3-1 and the lower die sleeve 3-2, ensuring that their adjustment is unaffected by the position of the screw hole. At this time, the end diameter of the positioning bolt 11 is larger than the width of the adjustment groove 12, and its end is in close contact with the wall surface of the upper die sleeve 3-1. Furthermore, the upper die sleeve 3-1 has a receiving groove 13, and the adjustment groove 12 is located within the receiving groove 13. This confines the bolt head of the positioning bolt 11 within the receiving groove 13, preventing the end of the positioning bolt 11 from protruding and hindering the subsequent connection of the punching die 3 to the steel component.

[0019] Furthermore, a receiving box 14 is detachably provided at the bottom of the punching die 3. The receiving box 14 is connected to the lower die head 16 located at the bottom of the punching die 3, and is used to receive round steel pieces that fall from the steel components, facilitating centralized collection and processing, and preventing the round steel pieces from spilling and causing abrasions or other safety hazards to passing personnel. Specifically, a placement groove 15 is provided at the bottom of the punching die 3, and the receiving box is slidably placed in the placement groove 15. The sliding placement facilitates the placement and removal of the receiving box 14, improving the convenience of operation. Preferably, the bottom surface of the receiving box 14 is higher than the bottom surface of the punching die 3. Since the punching die 3 is made of steel and the receiving box 14 is made of plastic, setting the bottom surface of the receiving box 14 higher than the bottom surface of the punching die 3 can avoid wear and tear on the receiving box 14 during use and extend its service life.

[0020] Under normal use, this invention operates on the same principle as the existing handheld punching machine 1. When space is limited and the operation of the punching machine 1 is affected after adjusting the position of the punching die 3, the positioning sleeve 4 can be moved upward to release the positioning sleeve 4 from the positioning sleeve 7. The punching die 3 can then be rotated to fit the outside of the steel component. Subsequently, the positioning sleeve 4 is released, and under the restoring force of the positioning spring 5, the positioning sleeve 4 re-engages with the connecting sleeve 7. When it is necessary to adjust the opening size of the punching die 3, the limiting position of the positioning bolt 11 is released, the positions of the upper die sleeve 3-1 and the lower die sleeve 3-2 are adjusted, and then the positioning bolt 11 is used to reposition them. This invention achieves technical improvement only by optimizing the connection method between the punching die 3 and the punching rod 2 and the matching positioning parts. It does not require complex modifications to the main structure and power system of the existing handheld punching machine 1. It has a simple structure, low manufacturing cost, and convenient installation and maintenance. At the same time, it is suitable for the operation scenario of punching round holes in existing steel components and can be directly applied to various processing or installation sites with limited space. It has a wide range of applications and strong practicality.
